Investigators searching for Teresa Halbach found human teeth and bones in a burn pit behind Steven Avery's garage, authorities said. Preliminary results Tuesday identified the remains as Halbach's, according to a criminal complaint charging Avery with first-degree intentional homicide and mutilation of a corpse.

Investigators found Avery's and Halbach's blood inside her SUV and her vehicle key, with Avery's DNA on it, hidden in Avery's bedroom, according to the complaint.
